BRAKE-HEAD FOR RAILWAY-CAR BRAKE-BE'AMS.

SPECIFICATION forming part of Letters Patent No. 740,092, datedSeptember 29, 1903.

Application Bled July 6, 1903.

To all whom, t may concern,.-

Beit known that I, SETH A. CRONE, a citizen of the United States, and aresident of New York, in the county of New York and State of New York,have invented. certain new and useful Improvements in Brake I-Ieads forRailway-Car Brake-Beams, of whichthe following is a specication.

The invention relates to improvelnents in brake-heads forrailway-carbrake-beams and it consists in the novel featuresandcombinations of parts hereinafter described,and particularly pointed outin the claims.

Brake-beams of the class towhich my invention pertains comprise abody-beam of suitable length, brake -Vheads on the ends thereof adaptedto receive the brake-shoes, and a fulcrum or strut for the brake lever,one division of brake-beams employing a fulcrum and the other or trussedbeams comprising a strut; and my invention has for its object to producea novel brake-head for the ends of the body-beam whether the latter be astructural beam or a flanged beam, the said brake head 4being efficientand capable of being firmly and quickly applied tothe ends of the beamand of receiving and rmly holding the brake-shoes.

The brake-head of my invention is formed from a blank or blanks offorged metal bent to the required shape and adapted to be secureduponthe end of the body-beam and to eectually receive and support thebrakeshoe;

The purpose of my invention is to materially improve brake-shoe headsand to produce a brakeshoe head capable of withstanding the severe usesto which brake-shoe heads are put and which shall be efficient anddurable and not likely at any time tobecoine fractured or broken.

The invention will be fully understood from.I

Serial No. 164.307. (No model) Fig. 2. Fig. l is aphorizontal section ofa `portion of saine on the dotted line et 4 of Fig. 2. Fig. 5 is adetached plan view of a blank employed in the formation of a part of,one desirable construction of the brake-head. Fig. 6 is a view, partlyshaped, of the blank from which the brake-head shown in Figs. l and 2 isformed; and Fig. '7 is an edge view of same.

In the drawings, l0 designates acustomary form of brakeshoe, ll acustomary form of body-beam, and l2 the brake-head of my invention, thishead being of forged metal and having the shoe lO secured to'it'by meansof the pin 13which is of usual form and construction.V p

The brake-head may be described as comprising an inner face portion 14.to receive the shoe l() and an outer face or portion 15 to be applied tothe body-beam ll. The inner face or portion of the brake-head is at itsends formed with the bearing-surfaces 16 for contact with the endsurfaces of the brakeshoe IO and at its central portion with thebearing-surface 17 for contact with the inner end of the central lug 18on said brake-shoe, while at the opposite ends of the saidbearingsurface 17 the said head is formed with the projecting pockets19, which lie at the upper and lower ends of the said lug 1S and attheir upper and lower ends are open in line with the usual opening inthe lug 18, so that the pin I3 may pass through said pockets 19 and lugI8, as shown in Fig. l, for the purpose of detachably fastening the shoe10 to the brake head. The pockets I9 are formedby slitting the metalblank on the lines 2O 20, Fig. 6, and depressingthe metal of the blankintermediate said lines, rso that said metal thus depressed shallconstitute a pocket or loop, this pocket` or loop having a closed outerend where it contacts with the shoe and closed sides, but open at itsupper and lower ends, so as to form a passage for the pin 13. respondexactly with each other, and their primary purpose is to affordprojections to Contact with the innergface of the shoe IO and to passinto line with the upper and lower ends of the lug 1S of said shoe, sothat the pin I3 may be applied for securing the shoe IO in position. Inthe preferred consame looking in the direction of thearrow in l Thepockets or loops 19 I9 cor-I IOO struction of the head I also make useof the loops or pockets 19 and pin 13 as a means for aiding in securingthe head and shoe to the body-beam 11, and in carrying out this featureof the construction, which is shown in Fig. 1, I first provide a blank2l, (shown in Fig. 5,) having projecting' end lips 22 and slits 23,these slits 23 substantially corresponding with the slits formed on thelines 2O preliminar)v to the formation of the loops or pockets 1f?. Theblank 21 when prepared as shown in Fig. 5 then has the metalintermediate the slits 23 22S depressed vinto the form of loops 21,corresponding with but smaller than the loops or pockets 19 of the head,and the said loops 2l of the plate or blank 21 are then inserted intothe said loops or pockets 19, as shown in Fig. 1, so that they may notonly strengthen the said loops or pockets 19, but afford a means forsecuring the plate 21 against the rear side of the front 1i of thebrake-head, said plate when so applied to the head leaving the lips 22projecting outwardly in position to be turned over upon the flange ofthe beam 1l, whereby to aid in securing the head to said beam and inrendering the entire structure more rigid and durable. \Vhen the loops21 of the plate 21 are inserted within the loops or pockets 1f) of thebrake-head, a double thickness of metal is provided intermediate the pin13 and the shoe 10 and also at the opposite edges of said pin, vwhichwhen in position will lock the plate 21 in its location and enable saidplate through its lips 22 to effectually bind against the flange of thebeam 11.

The front 14 of the brake-head is about on central lines traversing thepockets or loops 19 formed with shoulders 25, against which the endedges 26 of the plate or blank 21 may Contact, said shoulders 25formingin effect a recess to receive the body of the plate orblank 21and aid in securing the latter firmly in position. In instances in whichit maybe desired not to employ the plate 2l the recess formed by theshoulders 25 would directly receive the flange of the body-beam 10 andaid in centering the brake-head upon said fiange.

From the lower edge of the lower loop or pocket 1!) of the brake-headthe front face thereof curves downwardly and outwardly to thebearing-surface 16, at the lower end of which the plate or blank fromwhich the head is formed is turned upwardly upon itself to form onesection ,of the outer face portion 15 of said head, the two portionscontacting with each other below the lower loop or pocket 19 and beingbound together in the preferred construction by a tongue 27, formed fromthe metal of the blank and pressed outwardly therefrom and upwardlyagainst the saidouter portion 15 of the said brake-head. The lowersection of the outer portion of the brakehead passes upwardly to the webof the beam 11, where it is formed into a flange 28, adapted to besecured to said web and conforming to a flange 29, formed on the uppersection of .the outer portion 15 of said head.

From about the upper edge of the upper loop or pocket 19 the inner face14 of the head is curved inwardly to form the loop 30 and then upwardlyand out to the upper bearing-surface 16 for the shoelO, at the upperedge of which surface 1G the metal of' the blank or plate is folded overupon itself and carried downwardly to engage the outer surface of theloop and also to pass into engagement with the web of the beam 10, thisportion of the blank being formed integrally with the flange 29, throughwhich and the flange 28 the rivet 3l, for securing the head upon thebeam, may pass.

At the upper end of the brake-head is formed the eye 32, to which in theusual manner the suspending-chains may be attached, and this eye 32 is,like the tongue 27, formed from the metal of the blank out of which theentire brake-head is formed. In the formation of the eye 32 and tongue27 I slit the metal blank on the lines 33 for the eye 32 and on thelines 34 for the tongue 27 and then in forming the blank into a finishedhead press outwardly those portions of the metal between the slits andbetween the slits 3J( to form, respectively, the eye 32 and tongue 27.

rlfhe entire brake-head is when the plate 21 is not employed. formedfrom one strip or blank of forged metal first bent into the preliminaryoutline shown in Figs. f3 and 7 and then into the finished conditionshown in Figs. 1 and lVhen the plate 2l is made use of, the entirebrake-head is then formed of but two pieces of forged metal, and ineither construction the main body of the head is in one integral pieceof forged metal so shaped that it may effectually resist the strainslikely to come upon it and to eilieiently and properly receive, support,and maintain the shoe 10.

At the upper end of the head the metal of the blank may be stiffened andstrengthened, if desired, by, while cutting the slits 33, pressing themetal at the outer sides thereof outwardly to the position indicated bythe dotted lines 35 and then pressing the outer edges of this portion ofthe metal outwardly to form angle-iron flanges, which will appear in thefinished head at the upper end of the latter and at the opposite sidesof the eye 32.

The outer portion 1 5 of the head above described is shown as applied toa flanged beam 11; but in the construction of trussed beams thebody-beam is in the form of a channel or other structural shape, andwhen my brakehead is to be applied to this character of body-beams theends of the blank instead of being brought together to form the fianges2S 20 to engage the web of a fianged beam will be conformed fo the upperand lower surfaces of the channel or other structural beam without,however, other modifications in the general bodyof the forged-metalhead.

I prefer to form tle loops or pockets 19 and 2lin the mannerhereinbefore described, so
